The 2011 Heat were an example of boring, isolation basketball that resembled 90s-2000s ball, full of isolation basketball and physical defense..Spoelstra admitted that they did not work on their offense, at all, in their first season together, relying solely on the talents of Lebron/Wade..
In contrast, the 2011 Mavs were one of the most entertaining teams I have ever seen, they ushered in the new era of NBA ball IMO..mobile defenders with a complicated zone defense that required all-around defensive efforts, along with an unselfish superstar that agreed to play in an offensive system that promoted ball-movement, spacing and 3-point shooting..
The 2012 and 2013 Heat have followed suit, along with the 2013 and 2014 Spurs, the new Clippers, etc..moving the ball and playing elite team defense, rather than ugly, isolation, selfish basketball with vanilla schemes that we saw for most of the 90s and 2000s..
